Bright is an umbrella term for atheists, agnostics, freethinkers, or anyone else with a naturalistic worldview. Its proponents hope to use the term "bright" in much the same way as the gay community has appropriated the word "gay".

The ethics and actions of a bright are based on a naturalistic worldview

Antonym

The brights recently voted on a term for their use when referring to non-brights. The term adopted is "Super," as in Supernaturalist. The term was chosen as an antonym which would not convey the meaning of "not bright." Very few would object to being called "Super."

Criticism

Despite acceptance in some circles, the Brights' movement has also received a significant negative response both by religious and non-religious people. See, for instance, Chris Mooney's reaction on CSICOP, which discusses the negative reaction published by Christian conservative Dinesh D'Souza.
